起信論疏筆削記 19.32

19.32

一中，疏　障礙者，障入道人，礙令退故。堆惕精魅並如下說。三種者，魔鬼神也，一者違情五塵，或大或小恐怖萬端，故令失志；二者順情五塵，對男現女、對女現男，令其生染；三者平等五塵，揀去前二，即是此境。以魔鬼神之三種，各能現違、順、平等之事也。

Under the first, the commentary says: "Obstacles" means obstructing those who have entered the Path and hindering them so as to cause them to regress. Duitig demons and essences are discussed below. "Three kinds" refers to māras, ghosts, and spirits. First are the five sense-objects disagreeable to the feelings, which appear either very large or very small, terrifying in ten thousand ways, thereby causing one to lose one's resolve. Second are the five sense-objects agreeable to the feelings, manifesting a woman to a man or a man to a woman, causing them to generate defilement. Third are the five sense-objects that are neutral; excluding the former two, it is this state. Because the three kinds—māras, ghosts, and spirits—can each manifest disagreeable, agreeable, and neutral events.
